ACCESSING THE /source DIRECTORY

Example 1: Source some code and run a function

# Example 1: Note relative path, which can be read: Up one
# directory(..), down into source (/source), and 
# then "source" an R file (data_access.R)
source("../source/data_access.R")
data_access_test()
## [1] "Hello: World!"

Example 2: Initialize a variable and then use it

# Example 1: This function was "sourced" above
msg <- data_access_test(" Morgan!")

Hello: Morgan! Hope you have a good day!!

summary(cars)
##      speed           dist       
##  Min.   : 4.0   Min.   :  2.00

##  Max.   :25.0   Max.   :120.00

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.
